Product description

This section provides an overview of the principal technical data describing the ST87M01 narrow-band Internet of

Things (NB-IoT) and GNSS cellular module family. An ultra-compact, ultralow power, cost-efficient, certified NB-

IoT, and GNSS module family, offering multiband data transmission, is hereby introduced along with its super

compact form factor.

2.1

Overview

The ST87M01 is a high-performance, with ultralow power consumption, NB-IoT (LTE Cat NB2) 3GPP Release 15

and GNSS certified module family.

The ST87M01 module family supports multifrequency bands, with an extended multiregional coverage, enabling

almost complete worldwide NB-IoT data communication. In addition, the presence of the GNSS receiver allows to

support multiple satellite constellations to address high-accuracy localization applications.

Moreover, the ultra-compact module form factor makes the ST87M01 family the perfect choice for size critical

applications, allowing for miniaturization. In fact, the ultra-compactness is a crucial characteristic addressed by

the ST87M01 family, hereby presented in an LGA package of only 10.6 mm x 12.8 mm (with 51 pins).

Furthermore, thanks to the ultralow power consumption and industrial qualification grade over the industrial

temperature range, the ST87M01 family represents the best choice for a wide range of IoT applications: ranging

from smart grid, energy smart metering, smart city, factory automation, industrial IoT, and asset tracking to any

smart monitoring applications matching Low Power Wide Area Network (LPWAN) communication requirements.

In addition, the ST87M01 family can receive firmware updates and additional features via firmware upgrades over

the air with optimized firmware upgrade procedures (Differential FOTA).

STMicroelectronics may update the firmware provided with the modules at any time. STMicroelectronics

recommends that users regularly check for documentation and the current firmware version available at

www.st.com/en/wireless-connectivity/st87m01.html.

Additionally, the ST87M01 family embeds PDU SMS service and internet protocols for NB-IoT products, including

TCP/IP, TLS/DTLS, CoAP, LwM2M, MQTT, and HTTP/HTTPS, which enable a multiple and broad set of IoT

applications.

Lastly, full support of Power Saving Mode (PSM) and Extended Discontinuous Reception (eDRX) mechanisms,

along with ultralow power silicon technology adoption and a dedicated interface to wake up the module on an

interrupt-base, allow the ST87M01 family to achieve an extra long battery life on a single cell primary battery.

The ST87M01 family is designed and qualified according to industrial grade: each manufactured module is fully

tested, traced, and satisfies STMicroelectronics' stringent reliability and quality requirements, to meet the highest

levels of product quality and reliability for 15 years of long-term use in the field.

2.2

Safety information

The ST87M01 is typically used in well-defined applications such as metering equipment, however it can be used

in any application requiring NB-IoT connectivity so an assessment of the human risk associated with the usage of

an RF cellular terminal should be done, and precautions must be observed, in all phases of the operations of the

terminal incorporating the ST87M01, by the terminal manufacturer.

The terminal manufacturer must notify users and personnel of this safety information. STMicroelectronics is not

liable if the terminal manufacturer does not properly notify the user of the precautions.

The ST87M01 is compliant with the normative related to EMC, RF exposure, and electrical safety listed in

Section 5.2.1 Table 7, however the terminal manufacturer should verify the compliance with specific norms related

to the specific application, considering also the following general precautions:

•

Mobile communication equipment should not be used while driving according to specific laws and

regulations.

•

Wireless devices must be switched off on aircraft during the flight to prevent interference. More specific

restrictions should be verified by airline staff.

•

Wireless devices could create interference with some medical equipment.

•

Cellular communication cannot be ensured in all network conditions. Emergency communication can be

done only with adequate cellular signal strength.

•

RF interference can occur if the terminal is used close to radios, computers, or other electric equipment.

•

In areas with a risk of explosion, specific indications and signs must be followed.
